This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.

The quality of this manual is good. It has all schematics and setup information for both the MDS-B3 and the MDS-B4. The scan quality is quite good, all pages are readable, This service manual also contains scans of the operating instructions from the User manual.

Quick site processing. A complete and very useful manual with all details. Thank you!

Das Service Manual war von der ersten bis zur letzten Seite sehr informativ und hilfreich. Die Darstellung aller Teile war klar und der Text gut lesbar.
Vielen Dank, das war nicht der letzte Download bei ownner-manuals.com.

12. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz (FWD) and FWD SPEED ± 45Hz (REV). 13. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : Azimuth adjustment screw Method : Play back (FWD) the 8kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 14. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point :TP8(Lch), TP9(Rch) Method : Play back the 315Hz and 8kHz signals of the test tape and check that the output ratio of the 8kHz signal with respect to that of the 315Hz signal is within 5.0dB. 15. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8(Lch), TP9(Rch) Method : Play back the test tape and check that the output level of the test point is 110mV ± 3.0dB. 16. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz / 8kHz (LINE IN) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes -20VU (-26dBV). Record and play back the 1kHz and 8kHz signals and adjust SFRs so that the output of the 8kHz signals becomes 1.5dB ± 0.5dB with respect to that of the 1kHz signal. 17. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0VU (-6dBV). Record and play back the 1kHz signals and check that the output is -1dB ± 3.5dB.

18. µ-con OSC Adjustment Settings : � Test point : TP11(KEY-SCAN), GND � Adjustment location : L951 Method : Connect a frequency counter across TP11 and GND via a CR network filter. Then adjust L951 so that the test point becomes 184.94Hz ± 0.18Hz.
